PAPER CONSTRUCTION.

No Drawing.

Specification of Letters Patent.

To all whom it may concern:

Be it known that I, JEAN CARROTTE, a

dent of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Paper Construction, of which the following is a specification.

v This invention relates to improvements in paper construction and has for its principal object to construct a paper having high. tearing resistance quality. I

This invention is applicable to any of the The method of manufacturing consists primarily in passin around the drum upon which the pulp is ing received a woven fabric wherein the warp threads are extended longitudinally and parallel each to the other while the woof threads are woven through the warp threads in a diagonal or inclined position. The angle at which fabric is not defined. 'It is found that the the more 'acute angles of the position of the woof threads relative to the warp threads.

such as bond paper, a very fine threaded is adapted to the use for which the paper is designed. The closer the mesh the stronger the paper. The woven fabric 'is placed in the paper or fpulp body about midway in the process. 0 the manufacture of the in the course of manufacture is forced through all of the interthat the woven fabric becomes in a sense a constituent of the body of the paper.

Various degrees of strength are provided in this paper. WVherein an .increased I ad a second layer of fabric woven in the the second layer of fabric, care is taken to so dispose the layers that the warp threads extend parallel each to the other in the two cross the woof threads in the layer first applied. The two layers may be interposed in the pulpsimultaneously but I prefer to placethem successively, allowing a thin layer of pulp paper to be laid over the first layer of fabric. are thus constructed in the body of the paper, there is produced an article which it is practically impossible to tear.

While I have herein above described the use of two layers of cloth woven in the manner described, I wish to be understood as also claiming the use of a single layer of the said cloth in combination with a single layer of the cloth of the usual construction, wherein the warp and the woof threads are crossed at an anglc of 90 degrees, or perpendicular each to the other.

I amwell aware that papers have been manufactured wherein threads have been" placed between layers of paper and incorporated in the body thereof, also that woven Patented Aug. 39, 1914).

Application filed April as, 1909. Serial no. 491,772.

WVhen two-layers of the fabric so that the warp and woof threads are disposed in an angular relation other than that of ninety degrees, said layers being super imposed so that the woof threads of each layer are extended across the Woof threads of the other layer and the warp threads in both layers are parallel; the said fabrics being' woven with open mesh, and said paper being homogeneously formed and holding the fiber of said fabrics in fixed relation.
